Loudspeaker Centering Support Inner Wall Mount
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing loudspeaker structure is hindered by a large size and instability due to the traditional centering support piece, which affects miniaturization and sound quality, as the lead wire of the voice coil can strike the support piece under high power, causing distortion.
Innovation Solution
The loudspeaker design features a centering support piece with an annular wave-shaped structure, where the inner edge is fixed to a holder and the outer edge is adhered to the inner wall of the voice coil assembly, using a sticker for secure attachment, and the voice coil is suspended within a magnetic gap, reducing height and preventing lead wire strikes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If the centering support piece is adhered to the outer side of the voice coil, then the voice coil is stabilized, but the overall height of the loudspeaker increases
Solution Approach 1:
The centering support piece is repositioned from the outer side of the voice coil to the inner wall of the voice coil assembly, changing the spatial dimension of attachment. This dimensional repositioning allows the support piece to provide stabilization while occupying less vertical space, thereby reducing the overall height of the loudspeaker.
2Device complexity
If the centering support piece is adhered to the outer side of the voice coil, then the support structure is simplified, but the lead wire easily strikes the support piece under high power
Solution Approach 1:
The centering support piece is extracted from its traditional position on the outer side of the voice coil and repositioned to the inner wall of the voice coil assembly. This extraction and relocation eliminates the interference between the lead wire and the support piece, preventing strikes and maintaining acoustic performance stability under high power conditions.
3Strength
If adhesive is uniformly coated at the connection portions, then the cone and voice coil bobbin are fixedly connected, but the loudspeaker size increases
Solution Approach 1:
The centering support piece is relocated from the outer side to the inner wall of the voice coil assembly, changing the spatial arrangement. This repositioning reduces the vertical space required for the support structure while maintaining connection strength through proper adhesive application at the new location.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
This configuration reduces the loudspeaker's height, enhances stability, and prevents distortion by ensuring secure attachment of the centering support piece and preventing lead wire strikes, resulting in improved acoustic performance and miniaturization.
Implementation Method 1
the voice coil bobbin generates vibration by the electromagnetic induction effect so as to bring the vibration diaphragm to vibrate to generate sound
